TONGARIRO NATIONAL PARK, NEW ZEALAND - AUGUST 08: Steam spills from Mt Tongariro after the mountain erupted for the first time in over 100 years on August 8, 2012 in Tongariro National Park, New Zealand. Mt Tongariro erupted intermittently from 1855 to 1897. Although not an immediate threat to the community, the latest eruption may be the beginning of weeks, months or even years of volcanic activity.
